MOUNT INSTALLATION
WARNING: You must use the supplied AC adapter. The
correct orientation for the adapter is in a vertical or
floor mount position. To prevent electric shock, do not
use the AC adapter's polarized plug with an extension
cord, receptacle, or other outlet unless you can fully
insert the blades to prevent blade exposure.
Connect the supplied telescoping antenna to the base
unit's antenna jack. Your scanner's sensitivity to various
frequencies depends on its location and the antenna's
length. For best reception, adjust the antenna's length
as follows:
Frequency
25-54 MHz
108-174 MHz
216-225 MHz
225-406 MHz
406-1300 MHz
NOTE: If desired, you may also connect an external
base station antenna equipped with a BNC male
connector to the antenna connector. Please refer to the
section entitled "Connecting Antenna" for important
instructions and warnings.
NOTE: An external antenna is required for mobile operation.
